COTTON-PICKEB.

'to provi e a cotton picker wherein air suction generated by a rotary fan is employed for picking the cotton and depositing it into a bed earned by the cotton picker.

A further object .of this invention is to provide a cotton picker structure wherein the cotton is sucked inwardly through nozzles and a flexible member into the fan easing and forced outwardly therefrom into a retaining bed, and to provide a mesh work covering for the bed for preventing the cotton from being blown out of the bed.

A further object of this invention is to provide a novel form of nozzle structure for attachment to the outlets of the fans whereby the suction'hose may be positioned within the "retaining bed of the picker for unloadin the cotton therefrom through the fans an outwardly through the normal form of nozzle structure.

With the foregoing and other objects in view this invention consists in such novel features of construction, combination and arrangementof parts 'as will be hereinafter more fully described, illustrated in the accompanying1 drawings and claimed.

In descri ing the invention in detail reference will be had to the accompanying drawin wherein like characters designate like an corresponding parts throughout the several views, and in which Figure 1 is a plan view of the improved Fig; 2 is a side elevation showing parts thereof broken away. I

Fig. 3 is a rear elevation showing parts broken away. Fig. 4 is a detail view of the novel nozzle structure, and

of the cotton picker which is mounted upon suitable axles 2 and 3, upon which axles are mounted the ordinary type of supporting wheels 4. The supporting structure 1 has a platform 5 which a prime mover 6 is mounted. The

prime mover 6 may be any suitable type of.

The prime internal combustion engine. mover 6 is operatively connected to a shaft 7, through the medium of power transmitting means illustrated at 8. The shaft is provided for rotating a pair of suction fans 9, which are ositioned interiorly of casing 10 and 11. he fan casing 10 and 11 are carried thereby, upon.

supported in any suitable manner by the platform 5, and they "have spouts 12 and 13 communicating with their outlet openings respectively. The spouts 12 and 13 have their delivery ends positioned for-delivering cotton into a retaining bed 14:. p

Attached to the outer sides ofthe fan casings 10 and 11 are substantially conicalshaped hollow extensions 15, which extensions have flexible conduits" 16 connected to their apexed ends as shown at 17. The flexible conduits 16 have nozzles 18 mounted upon their outer ends. The nozzles 18are detachabl mounted upon the outer'ends of the flexib e conduits or hose 16 in any suitable manner, and they have handles 20 formed thereon. A closure structure 21 is provided which includes a pivotally mounted member. 22 having a closure plate 23 formedu on one end of the same which is adapted or closing the mouths of the nozzles 18 and preventing the inlet of cotton into the nozzle. The end of the lever 22 opposite to the end 23 is shaped to form a thumb rest as indicated at 24, so that the person carrying the nozzle 18 may by some pressure move the lever 22 u on its ivotal support 25, for moving the c osure p ate 23 out of alinement with the mouth of the nozzle. A spiral spring 26 is connected to the lever 22 and normal y holds the closure end 23 in a nozzle closing position.

A foraminous cover 30 is provided for the auxiliary nozzle structure illustrated at '32, has the ends of its branches 33 and 34 mounted over the delivery ends of the spouts 12 and 13 as indicated in dotted lines in Fig. 1 of the drawings. The cotton is then sucked by the operation of the fan through the conduits 16 into the fan casings forced outwardly through the nozzles 12 and 13 through the auxiliary nozzle structure 32 and discharged into a gin or any other suitable structure. The rear end of the retaining bed 14 is provided with an opening 35 through which the nozzle 32 extends.

In Fig. 4 of the drawings, a side elevation of the nozzle structure 32 is shown, part of which is illustrated in section to show the structure of the nozzle. The auxiliary nozzle 32 is composed of an inner section 36 which is formed of coiled wire, and an outer section 37 of duck or canvas which surrounds the inner coil section 36.-

In reducing the invention to practice, certain minor features of construction, combination and arrangement of parts may necessitate alterations to which the patentee is entitled provided such alerations are comprehended within the scope of what is laimed.

What is claimed is In a cotton picker structure, the combi nation, of a cotton receiving chamber, means for removing cotton from said chamber including a pair of air suction fans having outlet pipes, flexible members communicating with inlets of said fans, a forked noz zle, the arms of said nozzle connected to said outlet pipes, said flexible members extendin into said chamber whereby the cotton wi 1 be drawn therethrough into said fans and out through said forked nozzle upon operation of the fans.

In testimony whereof I afiix my signature in presence of two witnesses.
